EMBOSSING-DIE.

Specification of Iletters Patent.

Patented Apr.,8,19i9.

Application filed April 8, 1918. I Serial No. 227,268.

Be it known that I, CHARLES A. STIGKNEY, a citizen of the United States, and resident of Chattanooga, Tennessee, have invented certain new and useful Improvements in Embossing-Dies, of which the following is a specification. I 7

My invention relates to dies for embossing printing plates used in addressing machines, and the invention consists in the features hereinafter described and particularly pointed out in the claims.

' In the accompanying is a sectional view of a pair of dies taken in the direction longitudinally of the'line of embossings to be made in the plate, repredrawin'gs Figure] senting the first embossing action in th i printing plate.

Fig. 2 is a view similar to Fig.1, showing the second action or embossing about to be performed upon the printing plate.

'Fig. 3, is a plan view of the female die and showing in dotted lines the relative position of the previous embossing, and representing in dotted lines also the relation of the die to the previous embossing it being that the die action takes place at the same location and that the printing plate is moved step by step to have the successive embossings made therein.

d Fig. 4, is a perspective view of the female Fig. 5, is a perspective view of the punch. As shown in Fig. 4 the die face 1 has formed therein the groove or depression into which the metal of'the plate is forced to form the embossed character.

' In the present instance the character is the letter l but this of course is representative of any and all characters necessary to make up the alphabet or numerical system. At four points around the face of the die proj ections 2 are located. These projections are at thesides of the die face 1, and lie be tween the extended planes of the upper and lower edges 1 1" of the said die face, so that it will be observed the two projections at lower face" of the raised portion l punch which is of an area slightlyless than that these are separated by recesses 3 of considerable depth, these recesses lying beyond the side edges of the field or'plane face of the die in which the character forming recess is located.

7 This female die'illustrated in Fig. 4: cooperates with a punch 4 having the character forming ribor projection A conforming of course to the depression in the face 1 of the die. This rib or projection 4: is on the of the the areaof the plane face of the die 1 except'those areas'lying betweenthe'two upper projections and the twofllower projections. '1 l} i In action upon the metal of the plate being embossed 'it' willbe understood that the metalis free to be drawn through the spaces a, b," at 'top'and' bottom of the'die between the'upper pair of points 2 and between the lower pair of points 2 respectively, and this is in addition to the freedom which is permitted to the metal to be drawn between the points at the sides of the die.

The points 2 supportthe metal about the character being embossed in the plane of the body of the plate and prevent tipping of the base upon which'the character is formed thus avoiding the necessity of truing up. the line of characters after being formed.

Figs. 1 and 2 represent the action of the dies upon the plate. Fig. 1 illustrating the first embossing effect, and Fig. 2 the next embossing action about to take place, from which it will be seen that during the second embossing action the character which is already embossed will overlie, substantially the recess 3 at the side of the die and there will be no blanking out action of the dies on this embossed character. This is illustrated also in Fig. 3.

The shift of the plates being embossed relative to the dies is less than the width of the dies, and at each die action the metal of the plate where the widely separated points 2 contact therewith is maintained in the same plane with the body of the plate while the metal is free to be drawn through the spaces between the points.

Another effect which I secure by my im proved die is that close line spacing can be obtained, for it will be observed from Fig. 4 that the cove for forming the characters may ext-en .to a point nearly if not quite be tween the lower pair of projections and this may be t e se s wit e. 1 Of th letter in respect to the space between the upper pair of projections.

The four points support the metal of the plate as far removed from the character as po s b -v 1. A die for embossing characters in addressing plates having a die face With a a ac e forming groo e. the e n, and W t a proj c ion a jacen eac of the fo r co rs Q aid at ext n g a o he ame and ith e esse be ow t P an o h ie face between the pairs of projections at the s d s of sa d ace substant a ly d r b I ZFAdie for e b sing h a s in ddress ng Plat s ha n die. fa With aa act r form ng shea e he in, n Wi h proiee on adjacent ea hof the our 0 n r o aid fa extend ng bo th am wit rece s s belo t e Pla hi. the di ace bet e n he. pa r of proi e iq s at the s d s Q aid, fa e, th fate 9f the i ex en ngin bet een the. pp d w r pairs of projections and terminating sub,- stantially n. l ne Wit he utera es of Said pr jecti ns, u stan lly as d ibediehtihh s bstant a y as er pairs, and a.
